Compound rotary and/or linear motor
First Claim
1. A compound rotary and linear motor comprising(a) a first stationary magnet system comprising consecutive stator sections arranged along a predetermined axis, each stator section including a plurality of electrically separate consecutive magnets arranged in a ring, the magnetic poles of consecutive stator sections lying side by side in axial alignment;
- (b) a second magnet system comprising a rotor including at least one pair of magnet poles;
(c) said first and second magnet systems being interposed;
(d) means mounting said rotor for rotary movement about said axis and for linear movement along said axis; and
(e) an electronic control system responsive to control signals and adapted to sequentially energize said consecutive magnets of each stator section to rotate said rotor and to independently sequentially energize axially consecutive magnets to move said rotor axially;
(f) whereby said motor may independently generate rotary, linear and helical motions.

Abstract
A compound rotary and/or linear motor comprises two interposed magnet systems of which at least one is variable by an electronic control system to generate rotary and/or linear motion of the other. One of the two magnet systems consists of axially consecutive arrangements, preferably rings, of electrically separate magnet poles. The other magnet system contains at least one pair of magnet poles. The electronic control system is designed optionally or according to program to generate rotary motion by sequentially energizing consecutive magnets in a ring, to generate linear motion by sequentially energizing axially consecutive magnets and to generate a combined linear and/or rotary motion by sequentially energizing consecutive magnets forming a helix.
